Update DeviceOutputListener interface

Currently, DeviceOutputListener::StopListening() must be called once for
each call to StartListening(). This means that a listener might be
stopped and restarted in cases where it didn't need to be (e.g. when
switching between listening to the "default device ID", and the "current
default output device").

This CL updates DeviceOutputListener to support replacing a listener's
current device. This allows us to elide certain calls under the hood,
which should minimize gaps in the received reference output.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
